    A Pd<inf>81</inf>Si<inf>19</inf> bulk metallic glassy rod with a diameter of 4.5 mm was produced by water quenching the fluxed alloy. Despite a negative heat of mixing between Pd and Si elements and very simple components constituting the binary Pd-Si glass-forming system, structural heterogeneity was induced either by slow cooling of a liquid or sub-T<inf>g</inf> annealing of glassy ribbons. The sub-T<inf>g</inf> annealing experiments evidenced that a more ordered amorphous phase emerged from the original glassy matrix. Our work provides an alternative way to tune the microstructure of metallic glasses by subsequent thermal treatment on an as-prepared single glassy phase.
